Climate Scientists Forecast Permanently Hotter Summers

ScienceDaily (June 6, 2011) — The tropics and much of the Northern Hemisphere are likely to experience an irreversible rise in summer temperatures within the next 20 to 60 years if atmospheric greenhouse gas concentrations continue to increase, according to a new climate study by Stanford University scientists.

In the study, the Stanford team concluded that many tropical regions in Africa, Asia and South America could see “the permanent emergence of unprecedented summer heat” in the next two decades.

“According to our projections, large areas of the globe are likely to warm up so quickly that, by the middle of this century, even the coolest summers will be hotter than the hottest summers of the past 50 years,” said the study’s lead author, Noah Diffenbaugh, an assistant professor of environmental Earth system science and fellow at the Woods Institute for the Environment at Stanford.

The warnings from scientists just keep on coming. So what are we going to do about it?
